EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent N0. 780,927, dated January24, 1905.

Application filed April 27, 1904.. semi No. 205,114.

T alt whom it may concern: I Be it known that we, EUGENE T. WESTER-FIELD and RAN OLPH F. WESTERFIELD, cit'i, Zens of the United States, andresidents of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in ExtensionTables, of whlch the following s a specification.

c The invention relates to improvements in extension-tables; .and itconsists in the novel features and combinations of parts hereinafterdescribed, and particularly pointed out in the claims. Y

The object of the invention is to provide a very efficient, simple, andconvenient extension-table and one of a construction adapted to concealwithinitself extension-leaves (preferably folded) and upon the extendingofthe The invention will befully understood from v the detaileddescription hereinafter presented, reference being had to theaccompanying drawings, in which Figure 1 is a top elevation, partlybroken away, of an extension-tableconstructed in accordance with andembodying the invention;

the table being shown in its extended condition with theextension-leaves in position, one pair ofsaid extension-leaves beingillustrated by dotted lines. Fig. 2 is a longitudinal-section-of same onthe dotted line 2 2 of Fig. 1, both pairs of the extension-leaves beingshown in position.

Fig.3 is a like view of same, the table being shown in its contractedcondition with the pairs of extension-leaves con cealed below thetable-top. Fig. 4 is a bottom view of same. Fig. 5 isa longitudinalsection corresponding with Fig. 2, but showing the table in apartly-contracted position to indicate the automatic action of theextension-leaves in disappearing below the tablebracket which cooperateswith the extensionleaves; and Fig. 81s an enlarged sectional view on thedotted line 8 8 of Fig; 4 and illustrates the method of locking the endsof the table at the transverse rails of same whensaid ends are in theircontracted condition shown in Figs. 3 and 4. v

In the drawings, 10-11 designate the main table-tOpsections; 12 13, thelegs therefor,

and 14 15 the usual transverse rails respectively connecting the legs 12with each other and the legs 13 with each other and supporting said maintop'sections 1O 11.

At the center of the table is provided a transverse rail 16, supportedupon the upper end of a central leg 17 and upon the ends of the rail 16are secured the longitudinal bars or rails 18 19, which correspond witheach other and are provided upon their opposite edges with the dovetailguideways 20 21, receiving the correspondingly-grooved edges of thelongitudinal rails 22 23, respectively connected with the main endsections of the table, said rails 22 23 being in the'presentinstancelfastened at their ends to the end rails .15 1 1 andinterposedbars 24., extending transversely at the ends of the table between thetop sections 10 11 and said rails 22 23.

The table so far as hereinbefore specifically described may beconsidered as of ordinary construction in respect of the main end parts25 26, mounted upon legs and having rails 18 19, secured to thecross-bar or central transverse rail 16, serve as means for guiding therails 22 23 during the movement of the ends 25 26 of the table towardand from each other.

Our invention resides more'particularlyin the pairs of hingedextension-leaves 27 28 and I The facing edges of the top sections 10 11the means for automatically elevating said leaves during the separationof the table end sections 26 and for causing their automatic loweringand final disappearance during the contraction of the table or theshoving of said end sections toward each other.

The pairs of extension-leaves 27 28 correspond with each other, and eachpair comprises the leaves 29 30, hinged together at 31, Figs. 5 and 6,so that the leaf 30 may be folded inwardly over upon the leaf 29, asshown in Figs. 3 and 5. The leaves 29 have secured upon their undersides the cleats 32 and hinged pins. 33, Fig. 6.

The rails 22, connected with the end section 26, have secured upon theirouter edges the brackets 34, which have their downwardly and outwardlylongitudinally inclined surfaces 35 and preferably the upper horizontalsurfaces 36, and these brackets 34 receive upon them when the table isextended and during the outward and inward movements of the end section26 the cleats 32 of the extension-leaves 28, said cleats 32 when thetable is in its extended condition resting upon the horizontal surfaces36 of said brackets, as shown in Fig. 2, and said cleats being adaptedto ride down the said inclined surfaces 35 when the end section 26 ispushed toward the end section 25,

as shown in Fig. 5. The brackets 34 are applied to the outer edges ofthe outer rails 22, and they cooperate with the extensionleaves 28. Uponthe inner edges of the rails 23 are applied brackets 37, correspondingwith the brackets 34 and having the downwardly and outwardly inclinedsurfaces 38 and preferably the horizontal surfaces 39. The brackets 37cooperate with the pair of hinged leaves 27, and the leaves 27correspond withthe leaves 28, but are not connected therewith. Thehinged pins 33, carried by the leaves 29 of the pairs of leaves 27 28,extend downwardly into free apertures 40, provided in the stationaryrails 18 19, and the said pins hold the pairs of leaves 27 28 in properrelation to each other and also allow the tilting of said pairs ofleaves in the manner shown in Fig. 5 during the extension of the tableand also during its contraction or when the end sections 25 26 arepushed toward each other, whereby, for illustration, when the said endsections are being pushed toward each other and the inclined surfaces 3538 of the brackets 34 37 pass under the cleats 32 the outer ends of thethen-folded leaves 27 28 may of their own weight tilt downwardly, asshown in Fig. 5, and pass below the top sections 10 11 during thecontinued motion of the latter toward each other, the said inclinedsurfaces 35 38 finally passing inwardly from below said cleats 32 andleaving the folded extension-leaves 27 28 resting upon the stationaryrails 18 19 and movable rails 22 23, which is their position shown inFigs. 3 and 4.

are provided with lips 41, which when the table is extended and theextension-leaves 27 28 are in their upper position may be utilized tosupport the outer edges of the leaves 30, the pairs of leaves 27 28being in their folded position (shown in Fig. 5) when the table is firstextended and the leaves 30 thereof then being turned outwardly into theposition in which they are shown in Figs. 1 and 2, with the outer edgesof said leaves 30 resting upon said lips 41, as shown, the entiretable-top then being on one horizontal plane and at such time the leaves29 being supported horizontally by reason of the fact that the cleats 32then rest upon the upper horizontal portions of the brackets 34 37.

Those portions of the table at one side of the stationary transverse bar16 constitute substantially a duplicate of those portions of the tableat the opposite side of said bar.

The end sections 25 26 are each locked to the middle stationary portionof the table when the table is in its initial contracted condition byspring-catches 42 43, respectively secured to the ends of the rails 1918 and respectively adapted to engage the transverse rails 15 14, asshown in Figs. 4 and 8. The catches 42 43 may be disengaged from therails 15 14 when it is desired to extend the table either by the directapplication of the finger thereto or by means of a spring-pin 44, suchas shown in Fig. 8. It will be necessary to hold the catches 42 43 outof engagement with the 'rails 15 14 until the table-sections havestarted on their outward movement, and then said catches may bereleased, and in practical use it will be found to be convenient tofirst release one catch and extend its end of the table and then releasethe other catch and extend that end of the table.

The initial contracted condition of the table is represented in Figs. 3and 4, in which it will be seen that the pairs of leaves 27 28 are intheir folded position below the table-top and resting upon the rails 1819 22 23, that the brackets 34 for the leaves 28 have passed inwardlybeyond the cleats 32 of said leaves, and that the brackets 37 for thepair of leaves 27 have passed inwardly beyond the cleats 32 for saidleaves 27. In considering the operation of the table it may be assumedthat it is desired to pull the end section 26 outwardly, so as toutilize the leaves 28, and under such condition the attendant willrelease the catch 42 and pull the section 26 in a direction outwardlyfrom the table-section 25. The movement in an outward direction of thesection 26 will result in the rails 22 being drawn outwardly and in thebrackets 34 being carried ITO under the cleats 32 of the folded leaves28, v

the inclined surfaces 35 of said brackets first riding under the innerends of said cleats 32 and gradually tilting said ends and the inneredges of said leaves upwardly, and the motion of the section 26 beingcontinued the said surfaces 35 of said brackets will ride along undersaid cleats 32 and finally elevate the leaves 28 to their upperposition, the horizontal surfaces 36 then being under and maintainingsaid cleats and leaves, after which the leaf30 will be folded overoutwardly from the leaf 29 and its outer edges caused to rest upon thelips 41, connected with the top section 11, as shown in Fig. 2. Duringthe outward movement of the section 26 the brackets 34 tilt the foldedleaves 28 upwardly more and more as the top section 11 passes outwardlyfrom over said leaves. The table-section may then be extended outwardly,and as it is moved outwardly it will through the rails 23 cause thebrackets 37 to ride below the cleats 32 of the folded leaves 27 andeffect the elevation of said leaves, after which the leaf of the pair ofleaves 27 will be unfolded or turned outwardly and at its outer edgescaused to rest upon the lips 41 of the top section 10,

the table then being in its fully-extendedposition. (Shown in Figs. 1and 2.) When it is desired to contract the table and conceal theextension-leaves below thetop of same, the attendants will turn theleaves 30 over upon the leaves 29 and then push the end sections 25 26of the table toward. each other. During the contraction of the table thebrackets 34 will ride under the cleats 32 of the then-folded leaves 28and the brackets 37 will ride under the cleats 32 of the thenfoldedleaves 27, and as the inclined surfaces of said brackets reach and rideunder said cleats the folded leaves will tilt downwardly at their outeredges in the manner represented at Fig. 5, and finally the said bracketswill leave the cleats entirely and allow the folded leaves to settledown upon the rails 18 19 22 23, as shown in Fig. 3. During theextension of the table the inner edges of the leaves 27 28 firstgradually elevate, and during the contraction of said table the outeredges of said leaves are first acted upon to tilt downwardly. Theelevation-and depression of the leaves 27 28 are accomplishedautomatically merelyby the pulling apartof the table-sections 25 26. andthe shoving together of said sections.

The brackets 34 37 are in the nature of wedges in that their inclinedsurfaces during the extension of the table move the folded leavesupwardly and during the contraction of the table effect the downwardmovement of the inner edges of the leaves 27 28 to the stationaryportion of the table,and thereby per- 33 freely descend, so that theleaves may assume their lower horizontal position. The brackets 34 37are so disposed with respect to the cleats 32 that when the table is tobe extended the top sections 10 11 will separate to some little extentfrom each other before said brackets contact with said cleats andthatduring the final shortening movement of the table parts saidbrackets will leave or pass inwardly beyond said cleats in advance ofthe coming together of the facing edges of said top sections l0 11. Thebrackets 34 being at the outer sides of the sliding rails 22 may bemoved without danger of their contacting with the stationary transversebar 16; but since the brackets 37 are. secured to the inner edges of theinner rails' 23 and have to slide by the said bar 16 said bar is groovedor boxed, as at 45, to form passage-ways for said brackets 37.
